During recent years, there has been developed a catalog of radiolarians, under the direction and in collaboration with Dr. Jane K. Dolven. This directory is in continuous development and reviews the major radiolarians in the Norwegian Sea, Gulf of California and the Arctic Ocean. The catalog will be constantly expanded and selected as site for the International Association of Radiolarian Paleontologists, where both living and fossil Radiolarians will be discussed. Currently, over 500 radiolarian species are in the directory that covers species descriptions, illustrations, distribution, synonyms, and literature references.
